Ecological Distribution and Carbon Storage Estimation of Seagrass Bed in Caofeidian in 2024
摘要
Abstract
With the continuous increase of global carbon dioxide(CO2)concentration,climate change has become the most prominent environmental issue faced by human beings in the 21st century,and the"blue carbon"of coastal ecosystems has gradually attracted attention.Seagrass beds are one of the near-shore highly productive ecosystems with great potential for carbon storage and are an important component of"blue carbon".Through field sampling and experimental measurement,this study quantitatively estimated the carbon storage of seagrass beds in Caofeidian,and systematically analyzed the sources of uncertainty in the estimation process.The results show that:(1)Based on GF-2 remote sensing image data in June 2024,the area of 42.82 km2 of seagrass bed in Caofeidian,Hebei Province was defined by manual visual interpretation,UAV aerial photography and ship surveying.(2)The seagrass species is Eelgrass(formerly known as grass wrack);the height range of seagrass is 60~103 cm.and coverage ranges from 10%to 60%.(3)The biomass carbon density of seagrass beds varied from 0.05~0.19 Mg C/hm2,and the sediment carbon density ranged from 14.27~31.12 Mg C/hm2.(4)In 2024,the biomass carbon storage of seagrass bed was 490 tons,the sediment carbon storage was 8.89 × 104 tons,and the total carbon storage of sebaceous grass bed was(8.94±2.32)× 104tons.关键词
